A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a polygonal sidewall extending from the first end to the second end. The vessel further having a top, a bottom, at least one side, and an internal surface, and an outlet fluidly coupled with the bottom; and a chemical-resistant lining associated with the internal surface of the sidewall and being substantially flexible. A scrubber tank is supported by the frame and fluidly connected to the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.

The invention relates to a fuel tank (1), in particular a hydrogen tank, for a fuel cell system, having a monolithic base body (10) made of a metal alloy, wherein the base body (10) has a first inner layer (11) having a first inner structure and a second outer layer (12) having a second inner structure, which differs from the first inner structure, and wherein the first inner structure is formed from a metastable austenite and the second inner structure is formed from a martensite.

The present disclosure relates to a metal material for a container for storing high-purity hydrogen fluoride, and to a manufacturing method therefor. Specifically, the disclosure relates to a metal material for a container for storing high-purity hydrogen fluoride, and a manufacturing method therefor. The metal material includes a graphite layer on the surface of a metal substance, and nickel fluoride films formed in structural defect spaces within the graphite layer, so that corrosion resistance and scratch resistance are improved, and thus high-purity hydrogen fluoride, which is a corrosive gas, can be stored and transferred without being contaminated.

A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.

A hydrogen pressure vessel capable of preventing hydrogen-induced cracking of a cylinder is provided. In a hydrogen pressure vessel according to one embodiment, a gap part (G) in which an inner peripheral surface of a cylinder (10) is spaced apart from an outer peripheral surface of a lid (20) is provided between a female thread part (10a) of the cylinder (10) into which the lid (20) is screwed, and a resin seal member (30), and the cylinder (10) includes a first through hole (41) for discharging gas in the gap part (G) into a relief pipe (51) and a second through hole (42) for introducing gas containing oxygen into the gap part (G) formed therein.

A material at least partly coated with a passive film of fluoride formed by contact with a gas containing ClF.

A fibre composite cylindrical tank containing a pressurized fluid sealed by a boss seal, has at least one opening with diameter D0, and having an inner surface, sealed by a boss seal, wherein the boss seal includes a first boss section with diameter D1 larger than the opening diameter D0 and second boss section of diameter D0 equal to the opening diameter D0, and wherein the first section is leaned against the inner surface of the tank by the pressurized fluid, the second section fits the opening and a gasket of diameter D2 larger than the opening diameter D0 is placed on the second boss section.

A hydrogen storage system includes a hydrogen storage alloy containment vessel comprising an external pressure containment vessel and a thermally conductive compartmentalization network disposed within the pressure containment vessel. The compartmentalization network creates compartments within the pressure vessel within which a hydrogen storage alloy is disposed. One or both of the compartmentalization network and the pressure vessel may be formed by a 3D printing process, such as by Selective Laser Melting (SLM) and/or Direct Metal Laser Sintering (DMLS). The hydrogen storage alloy is a non-pyrophoric AB.sub.2 Laves phase hydrogen storage alloy having: an A-site to B-site elemental ratio of not more than 0.5; and an alloy composition including (in at %): Zr: 2.0-5.5, Ti: 27-31.3, V: 8.3-9.9, Cr: 20.6-30.5, Mn: 25.4-33.0, Fe: 1.0-5.9, Al: 0.1-0.4, and/or Ni: 0.0-4.0.

A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a sidewall extending from the first end to the second end. The vessel further has a top, a bottom, at least one side, an internal surface, and an outlet fluidly coupled with the bottom. A scrubber tank is supported by the frame and fluidly connected to the top of the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.
